Specification forming part of Letters Patent -No..116,021, dated June ,20, 1871.

To all lwhom 'it may concern Be it known that I, ALANSON GARY, ofthe city, county and State of N ew York, have invented a new and useful Improvement in` Couplings for Telegraph Wires and other Wires; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates toY a new and useful improvement in mode of coupling the ends oftelegraph or otherwires together; and it consists in a metallic sleeve, in which the endsof the wire are lapped past each otherand fastened, as hereinafter more fully described.

' In theaccompanying drawing, Figure l represents a longitudinal section of the sleevecoupling with the con ductin g-.wire placed therein ready for fastening. Fig. 2 isthe same section, showing 'the wires fastened and the coupling complete; Fig. 3 is a cross-section of Fig.

2 on the line x Fig. 4 is a cross-section of the sleeve-coupling (without the wires) taken .on the sameline..

Similar letters of reference indicate correl sponding parts.

A is the sleeve-couplin g, which is of oval or v of other suitable form, with a longitudinal orice for receiving the wires side by side, as seen in the drawing. rEhe longitudinal orifice is enllarged at one or more places, as seen at B, and

at such enlargements there is a transverse hole,

`are placed in the sleeve their ends may proj ect through and be afterward 'bent over the'ends of the sleeve, as'seen in Fig. 2. This is done for the purposeof strengthening the coupling; but.I do not conline myself to any particular number of enlarged spaces B or rivets D. A screw or screws may be used instead of a rivet or rivets, if desired; but I prefer riveting.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- l. A sleeve-coupling, A, for connectingv the Y ends DD of telegraph-wires, substantially as shown and described. v

2. llhe rivets E passing through the sleevecoupling A and between the wires D D, whereby said wires are forced into the spaces B of Vthe coupling, substantially as shown and described. ALAN SON CARY.
